Presentia C v2 KNX

KNX Presence Detector & Motion Sensor

A KNX presence detector senses whether people are in the room and automatically controls lighting, heating, or shading. Motion detectors only respond to movement; presence detectors also maintain output when people are stationary.

KNX Room Sensor & Multi-Sensor

A KNX room sensor measures multiple room parameters simultaneously: temperature, humidity, CO₂, brightness, and presence. Ideal for ventilation control, comfort regulation, and IAQ monitoring in offices and living spaces.

KNX Temperature Sensor

A KNX temperature sensor measures room temperature and sends it as a floating-point value (DPT 9.001) to the bus. Heating controllers, air conditioning units and switching actuators use this value for regulation, and a single sensor can supply multiple devices simultaneously.

KNX Motion Detector

A KNX motion detector senses movement within its detection area and sends a 1-bit telegram (DPT 1.002) to the bus. Unlike a presence detector, it reacts to rapid movements, ideal for corridors, stairwells and outdoor areas where short switching times are desired.

KNX Brightness Sensor

A KNX brightness sensor measures illuminance in lux (DPT 9.004) and sends the value to the bus. Blind controllers automatically lower roller shutters in sunlight, constant-light controllers maintain a steady light level in offices, regardless of daylight levels.
